AMD's 'Newcastle' Budget Athlon64 Chips Analyzed 266

Edward Scissorhands writes "CNET News.com reported on Thursday that AMD had released a new "budget" Athlon64 CPU. Appearing on the AMD roadmap under the codename of "Newcastle", these chips are identical to the 754-pin Athlon64 3200+ in every way except for the size of their L2 cache (512KB vs. 1MB). CNET suggests that some of these chips may be 3200's that don't pass QA as having full 1MB caches. Newcastle chips are about half the cost of their 1MB cached counterparts, though preliminary benchmarks from Anand indicate favourable performance/price."

    Kyle of HardOCP makes a bunch of speculations as to AMD's purpose for releasing these chips, and comes to basically the same conclusions that CNet does.

    He sugguests that these chips are also just the ones that only had partial working cache (a portion of the cache was working, the other portion was not) and to save money they are selling these as a "budget" chip. Seems like a good idea to me!

      That's pretty standard practice in hardware manufacturing. It also explains the reasons why some hardware (Radeon 9500, etc) can be "unlocked" and turned into the real thing. They don't actually test "every" part at first, just samples of a batch. If X% fail the full spec, the entire batch is remarked as reduced-spec parts. They they are individually tested at the lower spec. It stands to reason that a certain number of these part would have passed the more rigorous full-spec tests, thus us "cheap" buyers can sometimes get lucky and get a nice piece of hardware for a small price.

      • That's pretty standard practice in hardware manufacturing.

        Going back IIRC to the 386SX, which was a 386DX with a nonfunctioning (and hence deactivated) FPU....

          Argh. No.

          The 386SX was a completely and utterly different chip from the 386DX. The SX only had a 16-bit data path while the DX had a full 32-bit data path. This is not a minor change in the chip or board layout -- in fact, one of the major reasons that Intel released the 386SX was to reduce transition costs from 286 motherboards -- there's considerably less difference between 286 and 386SX than 286 and 386. The 386SX had no feature differences -- it was just slower.

          I believe what you're thinking of is 486DX vs 486SX. The 486DX was the first Intel chip (in the 80x86 line) to integrate the FPU onboard. The 486SX didn't have the FPU, or the FPU was disabled post-manufacture (most likely due to failures in the FPU module, while the rest of the chip was fine). This is something that can be done during product test.

          The funny thing about that was the poor schmucks who bought a 486SX and then decided they wanted the FPU after all... there was a second processor socket onboard, and when the "FPU" was plugged in it simply disabled the primary CPU completely -- the "FPU" chip was a full fledged 486DX. IIRC, there was another varient where the second CPU sat on top of the first CPU (and disabled it), but I can't recall for sure.
          • IIRC, there was another varient where the second CPU sat on top of the first CPU (and disabled it), but I can't recall for sure.

            Such a chip existed, but it was for upgrading older systems, like the 286 to a 486. Obviously because other parts of the chipset weren't as fast, the performance wasn't the same as a true mobo swap, but it was good enough for some people. Such upgrades usually used the 486slc2 chip. Information on these chips, much like the chips themselves, is a bit hard to find, but I remember

            • Evergreen made such an upgrade kit for 486 systems that allowed a low end Pentium CPU to run with the 486's motherboard limitations. They are still around and some info can be foun at their website [evertech.com]
              • Actually, from what I recall the Evergreen chip was really a 486DX running at 100 Mhz or higher. They just billed it as a pentium speed. Really I think it's fair because the very late production 486's (that is after pentiums were out for a while) weren't much slower than the early pentiums.

                On a totally pointless side note, I find it annoying that the plural for pentium isn't pentia as it should be.
          • The 386SX had no feature differences -- it was just slower.

            If i'm not sadly mistaken, the 386sx could only address up to 16megs of memory (24 address lines), where the 386DX could address a bit more (32 address lines) 4gigs of ram if i'm remembering correctly..

            Let's not forget the 486slc and dlc as well. Unlike the 486 sx/dx, this was more like the 286 / 386sx in the fact that it only had a 16-bit data path and could only address 16megs of memory. This was most annoying for largish companies who bought

              Of course, that was a complete non-issue at the time. I mean, who could possibly need more than 16 MB of memory?!?!? :)

              I do recall getting my 486DX up to 20MB of memory in the early 90s... there were very few people with more memory at the time, and I only got that much because my MB had 8 DIMM slots (4x4M, 4x512k).

This was the main reason I upgraded to a true 386dx that took simms, rather then my old sx-16 board that took both chips and sipps.

          • Actually, I thought that the 386SX was designed FOR THE 286 BUS! It wouldn't be hard to make an adaptor yourself, considering that there had to be less than 100 pins there. BTW, why won't Intel release a pin-compatible version of the Pentium M for Pentium 4 boards?

    after 2004, the 754-pin sockets will make way for their new 939-pin sockets. AMD has said that they will continue upgrades for 754-pin 64-bit chips up to i think 3700+ After that you will need to buy a 939 pin motherboards. Though I wonder what the shelf life for the 754 pins are, since not that many programs can even make use of 64bit cpus yet.

    This is a very good incentive to go 64 bit. I was thinking of getting a 2500 Barton, since my 1800 finally kicked it last week when the cooling fan gave out (this was right after a re-format, so the temperature monitoring system was not installed yet). However, since this came out, it might be a good time to go 64 bit. The chip still packs punch, so its not really what we would tend to think of when the term "budget" comes up (AMD Duron...Intel Celly). Plus, it won't be that expensive to replace if you take the OC too far.

      Yeah, it makes you reconsider that Athlon XP 2500+ purchase. 64-bit is temping, but you have to keep in mind that the 754-pinout on the chip is doomed. AMD already announced that they will move to a 939-pinout for most future 64s (Opterons are 940, so I assume they are just removing the "multiple-cpu" pin.) If that's the case, you may not have a very long upgrade path (3700?)

        I know some people are conecerned about having large upgrade paths but I find that I'm really not one of them any more.

        Usually by the time a processor drops in price enough that I think it'd be worth replacing an older CPU there is a new FSB or something that makes me want a new motherboard + ram to go with it.

        Lately when I've been buying computers I've came to the conclusion that Motherboard, Processor, and Ram are pretty much a package that will never be upgraded independantly (Short of adding more Ram). Unless I have a processor die I'm really not worried about changing it.

    Didn't we? Athlon 64 3000+ review [amdzone.com].

    In conclusion the Athlon 64 3000+ is one of the best CPUs AMD has never announced. It makes a sub $1,000 system that is 64 bit capable easy to reach, and is able to perform quite admirably even with half of the cache of the other AMD64 CPUs. Will AMD make more 512kb cache Athlon 64s in the near future? How long will Socket 754 continue? Is this 3000+ an overclocker of merit? Stay tuned. For now if you have been craving for a powerful and cheap system with 64 bit onboard then the Athlon 64 3000+ is your CPU. It has no competition in its class, and likely will not for months to come.

    The cache is allocated physically. It isn't a question of it having 1023 Kbytes instead of 1024 so then being sold as a 512K model...

      Cache is not all or nothing. Let's say 934k of 1024k work. Turn off 512k including all the non-working memory and voila -- sellable budget processor. AMD chose the 50% line arbitrarily -- they could have chosen 75% and gotten fewer, higher performance processors or 25% and gotten more, lower performance processors.

      They can't actually tell you how much of the cache works because OEMs like to sell identical machines, i.e. all with 512k cache, not 512k cache or more.
      • Wrong. It doens't work that way. They don't, on a processor by processor basis, go in and "disable" the random parts of any Cache area that failed testing.

      The cache is allocated in blocks. There are 2 512k blocks, and if there are bad cells in just one of them, it is disabled and the chip is sold with only 1 512k block enabled. If there are bad cells in both, they throw it away.
      • I don't know about this chip specifically, but for chips in general there would be more than just two blocks. In fact, it would probably be along the lines of 36 cells of 32K a piece. If any of these cells fail validation, you can disable them.

        So long as the number of busted cells is 4 or less (just using my example numbers here), you can sell the processor with 1024KB of cache enabled. Obviously, if there are no cells that are bad you still disable 4 of them to keep the parts consistant (OEMs don't wan

    I like this idea, and from a product-line standpoint, it's a good one. After the Athlon XP line started, I sort of missed the situation with the Thunderbird/Duron, where there was always a low-priced alternative for budget systems.

    Perhaps now they will create a sort of "64-bit Duron," a lower-priced and less-powerful version of the Athlon 64. This way, in the future, if I want to create a bargain version of a AMD64 computer for a family member or friend, or buy one, there is a cheaper processor available for such a system.

    I sort of missed having that alternative available; this creates a bit of processor nostalgia for me :p

    Dont you just love the way that AMD dropped this 64bit chip on the market - WITHOUT WAITING FOR MICROSOFT TO CATCH UP - Like, trust that Linux support alone will be enough to push this thing into the low-end 64bit market.

    And its selling like hot cakes - so the market is proving them right.

    Maybe it is a sign of things to come - hardware vendors pushing forward and bringing real innovation back into PeeCees, knowing that Linux alone will be there to support the innovations, and that Linux support is enough to drive sales.

    Remember how back in the good old days, Hardware makers (Commodore, Atari, Apple, etc) were free to introduce radical new hardware every 12 months, with no regard to operating software portability - they knew that the software guys were capable of keeping up back then.

    The current situation, with Microsoft being the sole supplier of OS's means that any new hardware has to conform to some horrid, and aging 'standard' invented back in the 80's, simply because Microsoft seems to be incapable of keeping pace with innovations in hardware.

    Well done AMD - for daring to break the status Quo, and for sticking one up Microsoft at the same time.
    • Linux isn't the only thing that supports it right now though - most Windows software companies should be considering purchase of one of these, if they haven't already bought one for each developer. Longhorn 64-bit has been available to anyone with an MSDN subscription for a while now, and the first to market apps with 64-bit versions of software will get a big boost in market share when Longhorn goes live.

        1) The 32 bit mode performance is pretty impressive anyway (so AMD were clever to hedge their bets here)

        2) The performance of Win32 code on Win64 base is WORSE than Win32 code on Win32 base using this processor.

        I dont trust Microsoft to fully support x86-64 till Intel comes to the party as well.

    Abit NF7: $100
    Total: $389
    A complete waste of money, especially after today.

    P4 3.2 system for comparison:
    P4 3.2 CPU: $366
    Asus P4C800-E: $164
    Total: $530
    Better than both of the above, but only by a few percent for most things.

    That was the situation last week. Including an Athlon 64, Athlon 64 FX, or P4Extreme in the examples would have been useless since they're insanely expensive.

    However:

    Athlon 64 system you can build now:
    Athlon 64 3000+ 512k cache: $230
    Gigabyte GAK8VT800M: $106
    Total: $336
    Yowza.

    So, to jump from the top-end Athlon XP to an entry level Athlon 64 actually saves you $53. I could have spent an extra $86 and got all this. The Athlon 64 system will now save you $194 over the best P4 Intel has to offer, and it will beat it (for virtually all applications.) Of course, if $336 is too much, you can still build a good Athlon XP system and cut costs dramatically, but $336 is very reasonable for building a brand new system. It'll be interesting when Intel gets it's P4Extreme down to a reasonable price, and AMD starts ratcheting up the Athlon 64 speeds.

    Proves it's always better to wait just one more week. I should have known that there would be major cuts in the 64-bit world soon after the processor debut.

    Hope all this is useful to anyone considering building a system. Keep in mind that 1gb of dual-channel DDR400 RAM is gonna run at least $150.

    All prices are PriceWatch.com and the Athlon 64 CPU price is from a link on AnandTech. I know PriceWatch prices are hard to get and you have to deal with shipping and all that.
    • Athlon XP 2500+: $83
      Abit NF7: $100 (I'd use an A7N8X Deluxe here, but...)
      A multiplier adjustment to up it to 2800+ speeds (I've heard the 2500+ is an underclocked 2800+): $0
      Total: $183
